There are different points of view on the death penalty in America’s society. Is the death penalty social correct? The controversy whether the death penalty is just or unjust has been a debate in United States. There are 747 people on death row, 21 women, 726 men according to death penalty organization. (deathpenalty.org). After the death penalty there is no life, you are simply executed. In my research proposal I will examine do people believe that punishing someone to death will worth. The statistic of age, race and religion of a people who are sentenced to death penalty will be searched throgh the paper. Also, I will be aware of safety and ethical issues involved for participants. The death penalty is the important problem in our world. In the United States, 23 people were executed in 2017, which is the second lowest number in more than a quarter century according to report from the Death Penalty information Center. The United States for the first time was not among the top five country in executions in 2017, according to Amnesty International, a human organization that opposes the practice. The United States ranked seventh internationally behind China, Iran, Saudi Arabia, Iraq, Pakistan and Egypt. I will present more background details of pros and cons of death penalty, how it works and what methods are used to execute prisoners. Different cases I will present to show different methods of execution and how in a case of wrongfully convicted men lack of further investigation can lead to death penalty. However those methods are not always reliable. In two different cases the death penalty violated the 8 th Amendment. The 8 th Amendment to the United States Constitution states: “Excessive bail shall not be required, nor excessive fines imposed, nor civil and unusual punishments inflected”.
